Seven years of work and seven months of traveling in space, the seven-minute gravity begins at the age of 16 in Argentina.
Seven years of work, seven months of space travel and a severity of almost seven minutes: The US probe InSight is finally ready to touch the surface of the Mars Monday through a very dangerous landing maneuver. The NASA engineers who continue to operate the ground do not have to cross their fingers: at Martian's entrances, with their storms, until the feet are in contact with the rock, everything has been programmed. hours in advance
It's even more cruel that InSight will be safe and sound Martian's surface will signal that it takes eight minutes to reach Pasadena, California's location control center. "Mars is nothing harder to certify, Mars is difficult," said Thomas Zurbuch, head of NASA's science section, on Sunday, which has approx. $ 1 million approved to explore the red planet.
Since 2012, for the first time, an artifact will be on the land of Mars, only after the NASA wisdom vehicle, the only red one on the current planet. The United States has put artifacts there only to invest these missions in the 2030s with the intention of preparing for the future invasion of human explorers.
But more than half of the 43 attempts executed by the space agency, Mars, by robots, satellites, and others have failed.
Faster than bullet
InSight Mars's atmosphere must be introduced at 7:47 PM GMT, to avoid obliquely flying the piece. Just rubbing it with the atmosphere, the temperature will rise rapidly to 1,500 ° C, but the probe is prepared by strengthening the heat shield to withstand the impact. The probe reaches 20,000 km / h, three times faster than the rifle bullet, and 10 km will have a 24 km radius.
Starting at a point in the Earth, after 480 million kilometers, "he wants to achieve a goal of 130,000 kilometers," says NASA. Four minutes and a hundred kilometers away, a parachute will open automatically, slowing down quickly. Then, after opening the heat shield, the device opens three feet and the parachute disappears.
"We will have a free fall for a moment, which is a terrifying thought for me," said Tom Hoffman, Head of NASA's InSight project. The fire emits rapidly its 12 retrochannels, slowing down at 8 km / h, while the device's decrease is greater than 365 kg. At 7:54 PM GMT, seven minutes after the first contact in the atmosphere, InSight should finally "knead".
Magma and temperature
At that time, "six and a half minutes of terrorism" were baptized, nothing, and no one was going to direct InSight to solve his career or to resolve the blame. "I'm very calm, but at the same time very nervous," said Hoffman. "We have made the mission to ensure the success of the mission, but you never know what will happen," he said lately, "recognizing that he has not been feeling very well".
Engineers and their colleagues, including many European scientists who have helped avant-garde tools that travel by InSight aboard, have to wait until 20h01 GMT to receive the first signal sent by us. There is no doubt that he was very well and well-stabilized at three feet. InSight will open later, slowly, solar panels to power your tools. From now on, a busy job program is waiting for you.
He has to listen to and analyze in March, millions of years ago, to explain the mysteries of his formation. To find out more about understanding the Earth's formation later on, it is the only rocky planet in the interior of the interior. InSight has a French seismometer concept, SIX, which will be set live in the Martian soil and will listen to its minimal vibrations: meteors, meteorites, earth moving, rock layers, deep magma movements. .
Another important instrument, German origin, is HP3, and requires excavation between 3 and 5 meters to reach Mars's surface temperature. The windshield sensors are Spanish designs.
